Abstract

Time-resolved photoluminescence of poly(p-phenylene vinylene) in the picosecond regime shows that the non-radiative decay rate increases with increasing polymer chain conjugation length and that the luminescence decay is much faster for excitation parallel to the polymer chain than for perpendicular excitation. The results provide evidence for bimolecular recombination processes. © 1987 IOP Publishing Ltd.
